LM2574HVM-ADJ Frequently Asked Questions (FAQ)
-
The maximum input voltage is 60V, but it's recommended to keep it below 50V for reliable operation and to prevent damage to the internal circuitry.
-
To ensure a stable and accurate output voltage, make sure to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a minimum capacitance of 22uF. Also, keep the input voltage ripple low and use a stable input voltage source.
-
The minimum input voltage required for the LM2574HVM-ADJ to operate is 7V, but it's recommended to keep it above 8V for reliable operation and to ensure the output voltage is within the specified tolerance.
-
The LM2574HVM-ADJ is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to prevent overheating and ensure reliable operation.
-
The output voltage of the LM2574HVM-ADJ can be calculated using the formula: Vout = Vref * (1 + R1/R2), where Vref is the internal reference voltage (1.23V), R1 is the resistance between the output and the adjust pin, and R2 is the resistance between the adjust pin and ground.
